Objective To study adverse drug events(ADEs)of busulfan the U.S.Food and Drug Administration Adverse Event Reporting System(FAERS),and to mine the potential ADE signals,so as to provide reference for the safe drug use in clinical practice.Methods Data from the first quarter of 2004 to the first quarter of 2023 were retrieved from the FAERS database,and ADE records for busulfan as a primary suspect drug were obtained through data cleaning and standardization of target drug names.Risk signals for busulfan ADEs were mined based on the reporting odds ratio method,the proportional reporting ratio method,and Medicines and Healthcare Products Regulatory Agency method.The information component method was used to assess the intense of the risk signals.The ADEs were systematically classified according to Medical Dictionary for Regulatory Activities(MedDRA),and two ranking sequence of busulfan ADEs were generated by signal occurrence frequency and signal intense,respectively.Results A total of 20 326 ADE records were collected,involving 5 615 patients with 556 related ADE signals,of which 117 were newly reported as compared to those in the drug instruction of busulfan.Male patients accounted for a higher proportion than female patients(40.71％vs.30.74％).The main population of patients were younger than 18 years old(31.56％).The reports were most reported by physicians(33.71％)and other health professionals(24.35％)as well as pharmacists(23.86％),mainly from the United States(29.69％),Japan(15.78％),and France(11.79％).The top five ADEs in terms of occurrence frequency were busulfan use in unapproved indications,hepatic veno-occlusive disease(HVOD),mucosal inflammation,cytomegalovirus infection,and graft versus host disease.The top five ADEs in terms of signal intense were HVOD,acute graft versus host disease,veno-occlusive disease,graft versus host disease,and chronic graft versus host disease.The ADE signals involves 23 system organ classes.The top three SOCs in terms of the number of ADE signals were infections/infestations,investigations and neoplasms benign/malignant/unspecified(include cysts and polyps).Conclusion When busulfan is used in clinic,attention should be paid to its adverse events in hepatic veno-occlusive disease,infections,graft versus host disease,neurotoxicity,and venous thromboembolism,which are likely to cause serious consequences.The clinical pharmacists can assist clinicians to make prevention plans in case of busulfan ADEs,so as to improve the safety of busulfan use in clinic.

Objective:To explore the characteristics of endothelial function in children with incomplete Kawasaki disease (IKD) of different ages and its relationship with coronary artery lesion (CAL).Methods:A total of 200 children with IKD admitted to the Affiliated Hospital of Jining Medical University from February 2020 to May 2022 were selected as the IKD group, and another 200 healthy children who underwent physical examinations during the same period were selected as the control group. According to the age of children with IKD, infants ( n=78) were classified as those under 1 year old, infants ( n=62) were classified as those between 1-3 years old, and preschool children ( n=60) were classified as those over 3-6 years old. The endothelial function characteristics of IKD children in different age groups and normal control group children were analyzed and compared. In addition, IKD patients were divided into CAL group ( n=110) and nCAL group ( n=90) based on whether CAL was merged. The age, carotid intima-media thickness (IMT), flow-mediated-dilation (FMD), carotid stiffness index (SI), nitroglycerin-mediated dilation (NMD), tumor necrosis factor α (TNF-α), C-reactive protein (CRP), brachial artery endothelial dependent dilation function (EDD) and other clinical data were compared between the two groups. Cox proportional hazards model was used for univariate and multivariate analysis to identify the risk factors for CAL in IKD patients. A column chart prediction model was constructed and evaluated. Results:There were statistically significant differences in FMD, NMD, SI, IMT, reactive congestion index (RHI), and EDD between IKD patients and normal control group children (all P<0.05). There were statistically significant differences in FMD, NMD, SI, IMT, RHI, and EDD among three groups of IKD children of different ages (all P<0.05). There were statistically significant differences in the proportion of children aged ≤3 years, TNF-α, CRP, SI, IMT, EDD, FMD, and NMD between the nCAL and CAL groups (all P<0.05). Age ≤3 years, elevated levels of TNF-α, CRP, SI, IMT, and EDD, as well as decreased levels of FMD and NMD, were independent risk factors for CAL in children with IKD (all P<0.05). The column chart prediction model had high discrimination, and the area under the curve for predicting CAL occurrence in children with IKD was 0.868 and 0.830, respectively. Conclusions:There are significant differences in endothelial function among children with IKD of different ages, and endothelial function is closely related to the occurrence of CAL. When endothelial function is abnormal, CAL is more likely to occur.

Objective:To compare the difference in measurement results and nursing time between wireless body temperature pulse measuring system and the traditional mercury thermometer combined with hand diagnostic method for measuring body temperature and pulse, to provide a reference for clinical selection of accurate and efficient vital sign measuring tools.Methods:A total of 74 patients hospitalized in the Orthopedics Department of the First Medical Center of the PLA General Hospital from March to August 2022 were selected using a randouized coutrolled study. The body temperature and pulse data of every patients were collected by mercury thermometer + manual diagnosis and wireless body temperature pulse measuring system at the same time, and the measurement results and nursing time of the two methods were compared.Results:The temperature and pulse measured by the wireless body temperature pulse measuring system were (36.31 ± 0.52) ℃ and (78.27 ± 14.06) times/min, which were no significant different than (36.34 ± 0.51) ℃ and (78.57 ± 13.79) times/min by the mercury thermometer + manual diagnosis ( t = -1.54, 1.88, both P>0.05), and the two groups of data were significantly correlated, ( r = 0.940 and 0.995, both P<0.01). The daily nursing work time of the wireless body temperature pulse measuring system was (67.29 ± 5.15) min, which was significantly lower than (131.57 ± 6.58) min by the mercury thermometer + manual diagnosis ( t = 20.35, P<0.01). Conclusions:The wireless body temperature pulse measurement system is accurate in data collection, easy to operate, safe to use, less time-consuming in nursing work and worthy of clinical promotion.

Objective:To explore the risk factors for death within 1 year after hip fracture surgery in the elderly.Methods:A case control study was made on the clinical data of 551 elderly patients with hip fracture treated in Second Affiliated Hospital of Soochow University from January 2019 to December 2020, including 182 males and 369 females; aged 65-100 years [80(73,86)years]. Joint replacement, cannulated screw fixation or proximal femoral nail fixation were performed. The patients were divided into survival group ( n=494) and death group ( n=57) based on the death within 1 year after surgery recorded at postoperative telephone follow-up. The gender, age, hypertension, diabetes, cardiovascular diseases, chronic respiratory diseases, neurological diseases, chronic renal failure, anemia on admission, fracture types, American anesthesiologist Association (ASA) classification, operative methods, preoperative waiting time, duration of operation and perioperative blood transfusion were recorded in two groups. Univariate Cox regression was used to analyze the correlation between the above indexes and death within 1 year after surgery. All indexes with P<0.2 in the univariate analysis were included in multivariate Cox regression analysis to clarify the independent risk factors for death within 1 year after surgery. Results:Univariate Cox regression analysis showed that death within 1 year after surgery correlated with gender, age chronic respiratory diseases, chronic renal failure and anemia on admission (all P<0.01), but not with hypertension, diabetes, cardiovascular diseases, neurological diseases, fracture types, ASA classification, operative methods, preoperative waiting time, duration of operation or perioperative blood transfusion (all P>0.05). Multivariate Cox regression analysis showed that male ( HR=2.08, 95% CI 1.20, 3.61, P<0.01), age ≥ 80 years ( HR=2.22, 95% CI 1.15, 4.28, P<0.05), chronic respiratory diseases ( HR=2.54, 95% CI 1.19, 5.40, P<0.05), chronic renal failure ( HR=4.57, 95% CI 1.27, 16.44, P<0.05), anemia on admission ( HR=2.82, 95% CI 1.38, 5.76, P<0.01) were significantly associated with death within 1 year after surgery. Conclusion:Male age≥ 80 years, chronic respiratory disease, chronic renal failure and anemia on admission are independent risk factors for death within 1 year after hip fracture surgery in the elderly.

Objective:To investigate the early clinical outcomes of a minimally invasive anterolateral approach (Orthopadische chirurgie munchen, OCM) versus a conventional (posterolateral approach, PLA) hemiarthroplasty in the treatment of senior femoral neck fractures.Methods:A retrospective analysis was performed on 90 elderly patients with femoral neck fractures who received anterolateral and posterolateral approaches for hemiarthroplasty in the Second Affiliated Hospital of Soochow University from December 2019 to June 2021 and were followed up. In the OCM group, there were 45 cases, including 18 males and 27 females, aged 83.33±5.29 years (range, 76-96 years); In the PLA group, there were 45 cases, including 13 males and 32 females, aged 81.87±5.00 years (range, 75-94 years). Postoperative, surgical indices, perioperative bleeding, and soft tissue injury were assessed; pain was assessed using the visual analogue scale (VAS), and hip function was evaluated using the Harris score and the University of California at Los Angeles (UCLA) score.Results:The incision length, postoperative hospital stay, hemoglobin reduction, and occult blood loss were lower in the OCM group than in the PLA group ( P<0.05), but there was no significant difference in intraoperative bleeding and postoperative transfusion rate ( P>0.05). Serum creatine kinase and C-reactive protein levels (232.98±83.70 IU/L and 81.67±48.85 mg/L) were lower in the OCM group than in the PLA group (296.93±124.58 IU/L and 104.79±36.75 mg/L) 1 day after surgery, and the differences were statistically significant ( t=2.86, P=0.005; t=2.54, P=0.013). Postoperative pain was significantly improved in all patients, and VAS scores were lower in the OCM group than in the PLA group at 12 h, 24 h, and 48 h postoperatively ( P<0.05). The time to get out of bed after surgery was 20.73±4.99 h in the OCM group compared with 41.69±13.58 h in the PLA group, with a statistically significant difference ( t=9.71, P<0.001). Harris scores (63.31±6.21 and 75.76±4.91) and UCLA scores (1.84±0.42 and 3.69±0.76) were higher in the OCM group on the day of discharge and at 1 month postoperatively than in the PLA group (52.69±10.01 and 71.33±3.66); (1.62±0.54 and 3.16±0.80) points, all with statistically significant differences ( P<0.05). However, the differences in Harris score and UCLA score between the two groups at 6 months postoperatively were not statistically significant ( P>0.05). There were two cases of intermuscular vein thrombosis in the OCM group, with a complication rate of 4% (2/45), and one case of dislocation in the PLA group, with a complication rate of 2% (1/45), there was no significant difference between the two groups ( P=1.000). Conclusion:The minimally invasive anterolateral approach is a more ideal procedure for elderly patients with femoral neck fractures undergoing hemiarthroplasty. It has the advantages of a short incision, small soft tissue damage, low occult blood loss, early removal from bed, a short postoperative hospital stay, an improvement in pain, and a good early recovery of hip function.

OBJECTIVE To explore the relationship between laryngeal morphology and clinical function after partial laryngectomy for glottic laryngeal cancer,as assessed by CT.METHODS This study included 90 patients with glottic laryngeal cancer who underwent partial laryngectomy between March 2020 and March 2023(observation group).Postoperative follow-up included CT scans,measuring glottal area(GA),glottal width(GW),glottal depth(GD),subglottic area(SGA),and hyoid-cricoid distance(HCD).Postoperative respiratory,phonation,and swallowing functions were recorded.The study compared CT morphological parameters and voice acoustic parameters between the observation group and 50 healthy volunteers(control group)and analyzed the correlation of laryngeal CT morphological parameters with decannulation time,swallowing function grading,and voice acoustic parameters.RESULTS All 90 patients were decannulated at follow-up,with decannulation times ranging from 7 to 22(14.35±3.67)days.Laryngoscopy showed that 58 patients had complete glottal closure while phonating/i:/,whereas 32 had incomplete closure.At follow-up,all patients were able to eat orally.Swallowing function assessment results were:grade 0 in 62 cases(68.89％),grade 1 in 23 cases(25.56％),and grade 2 in 5 cases(5.55％).Postoperative laryngeal CT in the observation group revealed varying degrees of structural deficiencies in the vocal cords,laryngeal ventricle,and ventricular band.Glottal morphology appeared as'V','U'shaped,or irregularly abnormal,with some patients showing slight enlargement or deviation of the glottal slit.CT morphological parameters GA,GW,GD,SGA,HCD in the observation group were all smaller than those in the control group(P＜0.05).Those in the observation group with complete glottal closure during/i:/phonation had larger GA,GW,GD,SGA,HCD than those with incomplete closure(P＜0.05).Voice acoustic analysis revealed that postoperative F0,MPT were lower in the observation group compared to the control group(P＜0.05),while Jitter and Shimmer were higher(P＜0.05).Spearman correlation analysis showed a negative correlation between postoperative laryngeal CT morphological parameters GA,GW,GD,SGA,HCD and swallowing function grading in the observation group(P＜0.05).Pearson correlation analysis showed a positive correlation of these parameters with F0,MPT(P＜0.05),and a negative correlation with decannulation time,Jitter and Shimmer(P＜0.05).CONCLUSION Laryngeal CT morphological parameters GA,GW,GD,SGA,HCD are closely related to respiratory,phonation,and swallowing functions in patients after vertical partial laryngectomy for glottic laryngeal cancer.These parameters can be helpful in guiding clinical treatment and rehabilitation training.

Inclusion criteria were as follows: (1) gastric adenocarcinoma confirmed by preoperative gastroscopy;(2) preoperative imaging assessment indicated that R0 resection was feasible; (3) preoperative assessment showed no contraindications to surgery;(4) esophagojejunostomy planned during the procedure; (5) patients volunteered to participate in this study and gave their written informed consent; (6) ECOG score 0–1; and (7) ASA score I–III. Exclusion criteria were as follows: (1) history of upper abdominal surgery (except laparoscopic cholecystectomy);(2) history of gastric surgery (except endoscopic submucosal dissection and endoscopic mucosal resection); (3) pregnancy or lactation;(4) emergency surgery for gastric cancer-related complications (perforation, hemorrhage, obstruction); (5) other malignant tumors within 5 years or coexisting malignant tumors;(6) arterial embolism within 6 months, such as angina pectoris, myocardial infarction, and cerebrovascular accident; and (7) comorbidities or mental health abnormalities that could affect patients' participation in the study. Patients were eliminated from the study if: (1) radical gastrectomy could not be completed; (2) end-to-side esophagojejunal anastomosis was not performed during the procedure; or (3) esophagojejunal anastomosis reinforcement was not possible. Double and a half layered esophagojejunal anastomosis was performed as follows: (1) Open surgery: the full thickness of the anastomosis is continuously sutured, followed by embedding the seromuscular layer with barbed or 3-0 absorbable sutures. The anastomosis is sutured with an average of six to eight stitches. (2) Laparoscopic surgery: the anastomosis is strengthened by counterclockwise full-layer sutures. Once the anastomosis has been sutured to the right posterior aspect of the anastomosis, the jejunum stump is pulled to the right and the anastomosis turned over to continue to complete reinforcement of the posterior wall. The suture interval is approximately 5 mm. After completing the full-thickness suture, the anastomosis is embedded in the seromuscular layer. Relevant data of patients who had undergone radical gastrectomy in the above 12 centers from June 2021 were collected and analyzed. The primary outcome was safety (e.g., postoperative complications, and treatment). Other studied variables included details of surgery (e.g., surgery time, intraoperative bleeding), postoperative recovery (postoperative time to passing flatus and oral intake, length of hospital stay), and follow-up conditions (quality of life as assessed by Visick scores).Result:[1] From June 2021 to September 2022,457 patients were enrolled, including 355 men and 102 women of median age 60.8±10.1 years and BMI 23.7±3.2 kg/m2. The tumors were located in the upper stomach in 294 patients, mid stomach in 139; and lower stomach in 24. The surgical procedures comprised 48 proximal gastrectomies and 409 total gastrectomies. Neoadjuvant chemotherapy was administered to 85 patients. Other organs were resected in 85 patients. The maximum tumor diameter was 4.3±2.2 cm, number of excised lymph nodes 28.3±15.2, and number of positive lymph nodes five (range one to four. As to pathological stage,83 patients had Stage I disease, 128 Stage II, 237 Stage III, and nine Stage IV. [2] The studied surgery-related variables were as follows: The operation was successfully completed in all patients, 352 via a transabdominal approach, 25 via a transhiatus approach, and 80 via a transthoracoabdominal approach. The whole procedure was performed laparoscopically in 53 patients (11.6%), 189 (41.4%) underwent laparoscopic-assisted surgery, and 215 (47.0%) underwent open surgery. The median intraoperative blood loss was 200 (range, 10–1 350) mL, and the operating time 215.6±66.7 minutes. The anastomotic reinforcement time was 2 (7.3±3.9) minutes for laparoscopic-assisted surgery, 17.6±1.7 minutes for total laparoscopy, and 6.0±1.2 minutes for open surgery. [3] The studied postoperative variables were as follows: The median time to postoperative passage of flatus was 3.1±1.1 days and the postoperative gastrointestinal angiography time 6 (range, 4–13) days. The median time to postoperative oral intake was 7 (range, 2–14) days, and the postoperative hospitalization time 15.8±6.7 days. [4] The safety-related variables were as follows: In total, there were 184 (40.3%) postoperative complications. These comprised esophagojejunal anastomosis complications in 10 patients (2.2%), four (0.9%) being anastomotic leakage (including two cases of subclinical leakage and two of clinical leakage; all resolved with conservative treatment); and six patients (1.3%) with anastomotic stenosis (two who underwent endoscopic balloon dilation 21 and 46 days after surgery, the others improved after a change in diet). There was no anastomotic bleeding. Non-anastomotic complications occurred in 174 patients (38.1%). All patients attended for follow-up at least once, the median follow-up time being 10 (3–18) months. Visick grades were as follows: Class I, 89.1% (407/457); Class II, 7.9% (36/457); Class III, 2.6% (12/457); and Class IV 0.4% (2/457).Conclusion:Double and a half layered esophagojejunal anastomosis in radical gastrectomy is safe and feasible.

Objective:To systematically review the effect of fracture liaison service (FLS) in elderly patients with fragile hip fractures, so as to provide reference for clinical decision-making.Methods:By combining subject terms and free terms, electronic searches were conducted on China National Knowledge Infrastructure, WanFang Data, VIP, China Biomedical Literature Database, PubMed, Embase, Cochrane Library and Web of Science. The included references were manually retrieved using the snowball method. The retrieval time was from the establishment of the database to March 1, 2023. Two researchers screened articles based on inclusion and exclusion criteria, extracted data, and evaluated the quality of articles, using RevMan5.4 software for statistical analysis.Results:A total of 15 articles were included, totaling 4 333 patients with fragile hip fractures, with a follow-up time of ≥3 months. Meta-analysis showed that FLS could improve patient medication compliance [ RR=2.32, 95% CI (1.74, 3.11) , P<0.01] and hip function [ SMD=1.20, 95% CI (0.93, 1.47) , P<0.01] , reduce mortality [ RR=0.70, 95% CI (0.58, 0.84) , P<0.01] and the occurrence of refractures [ RR=0.44, 95% CI (0.32, 0.61) , P<0.01] , with statistical differences. Conclusions:Compared with routine nursing for fragile hip fractures, FLS can improve medication compliance and hip function, decrease mortality and the occurrence of refractures in patients with fragile hip fractures.

Objective:To evaluate the risk factors for diaphragmatic dysfunction of patients with sepsis and septic shock, and the application value of bedside ultrasound.Methods:Patients with sepsis and septic shock in the Intensive Care Unit (ICU), General Hospital of Ningxia Medical University from January 2020 to May 2021 were prospectively recruited as the research subjects, general postoperative patients and healthy volunteers were admitted as postoperative control and normal control groups. General clinical data were collected, patients with sepsis and septic shock were dynamically observed high sensitive c-reactive protein (hs-CRP), interleukin-6 (IL-6), serum albumin, transferrin, prealbumin levels, blood lactate, Pcv-aCO 2, ScvO 2, etc.; and indirect calorimetry was used to measure the resting energy level of the patient to calculate the missing energy value. Bedside ultrasound was used to dynamically evaluate the changes of diaphragm excursion (DE),inspiratory diaphragm thickness, and expiratory diaphragm thickness, to calculate relevant parameters. DE<10 mm or diaphragmatic thickness fraction (DTF) < 20% was diagnosed as diaphragmatic dysfunction. Results:(1) On day 1 in the ICU, the DE of the septic shock group, sepsis group and postoperative control group were significantly lower than that in the normal control group [10.3 (9.0, 13.6) mm, 12.3 (9.1, 15.0) mm, 12.9 (10.5, 15.7) mm vs. 22.0 (16.0, 24.6) mm, all P<0.05], and the incidence of DTF<20% was significantly higher than in the normal control group (32.7%, 41.9%, 33.3% vs. 0 %, all P<0.05), and the incidence of DE<10 mm in the septic shock group and sepsis group was significantly higher than that of postoperative control group and normal control group (36.7%, 35.5% vs. 10.0%, 0%, respectively, all P<0.05). On day 7, the DE in the septic shock group was significantly lower than that in the sepsis group [10.5 (6.8, 13.5) mm vs. 14.4 (10.6, 18.6) mm, P<0.05].(2) Correlation analysis of each index: The DE of patients with sepsis and septic shock on day 1, 3, and 7 was negatively correlated with the hs-CRP ( r=-0.253, -0.436, -0.455, all P<0.05); On day 3, DE was also negatively correlated with IL-6 ( r=-0.338, P=0.009); and DTF was negatively correlated with hs-CRP ( r=-0.375, P=0.004). On day 1, there was a positive correlation between DTF and serum transferrin levels in patients with sepsis and septic shock ( r=0.221, P=0.049). On day 3 and 7, the DE was positively correlated with serum prealbumin levels ( r=0.318, 0.408, both P<0.05). Conclusions:Patients with sepsis and septic shock have developed diaphragmatic dysfunction on day 1 in the ICU, which is mainly manifested as decreased in diaphragm mobility and diaphragmatic thickness fraction, and is related to inflammation and high protein catabolism.
